YOSHIMURA LETTER TELLS TRIAL OF RIFT

OAKLAND, Calif, Jan. 1—A letter describing the demise of an underground group just before the arrest of Wendy., Yoshimura and Patricia Hearst was among the last pieces of evidence presented this week by the prosecution as it completed its case in Miss Yoshimura's trial.

The letter, written in miss Yoshimuras hand and addressed to “Dearest Brother disclosed serious ruptures in the relationship between Miss Yoshimura and Miss Hearst, on the one hand, and two Symbionese Liberation Army members, William and Emily Harris, on the other.

In describing the S.L.A., however, the letter said: “I truly feel that what motivated them to take on armed action is very different from what motivated me and the others.”

Miss Yoshimura, 33 years old, has been charged with the illegal possession of explosives and weapons discovered in a Berkeley garage in 1972. The defense has conceded that she rented the garage but has argued that she did not know explosives and weapons were stored there.

The letter was found in the San Francisco apartment where Miss Yoshimuraand Miss Hearst were arrested Sept. 18, 1975. It was read to the jury by Jeffrey Horner, Deputy District Attorney of Alameda County.

“Ever since the group came together around these people a little over a year ago,” the letter said, “we've had a very, trying time” because of “sensationalized., media play on those people affecting our, heads.”

‘Very Different From Me’

In an apparent reference to Mr. and Mrs. Harris and Miss Hearst, the letter said: “My experience during the summer made me realize that they (two in particular—not P.H.) in fact are very different from me, and personally, I did not much like them.

“In spite of it I decided to stick with it because of their fierce dedication, knowing there were others waiting to, work together, and I was under their spell.”

The letter described difficulty with “in terpersonal dynamics” and widely differing views on what direction to take, but said, “We were finally able to do a couple of actions.”

Relationships broke down again, the,,, letter said, “when there were a series of incidents that took place which made, it very clear to particularly J., K., P.H. and me that we wanted no part of it and had “decided to go our own way.”

J. and K. were not identified in the letter.

The letter said that the breakup was the fault of two people who were not named but were presumably Mr.. and Mrs. Harris.

Mr. and Mrs. Harris were involved with Miss Hearst in a shooting at a sporting goods store in Los Angeles after Mr. Harris was accused of shoplifting. A short’ time later, six other S.L.A. members died in a fire after a gun battle with the police.

The letter said: “P.H. was hated by. our ‘leader’ for being so ‘rebellious,’ “ and added: “I hope you have a chance to meet P.H. She is incredible! She amazes me I swear only the toughest could have come out of it as she did. What an ordeal she went through!! What an ordeal all of us went through!! I can write a book about it.”

The letter, which was signed only “Me,” was one of 250 pieces of evidence that the prosecution introduced in its attempt Ito link Miss Yoshimura to the Berkeley arms cache.

A number of items bearing Miss Yoshimura's fingerprints and taken from the partment she and Miss Hearst shared a farmhouse in Pennsylvania, were introduced as evidence. Among them was a .38‐caliber revolver discovered in Miss Yoshimura's purse when she was arrested.

The prosecution also introduced ammunition, bomb material and weapons found in the Berkeley garage, including the floor plans and 24 photos of the summer home of former Defense Secretary Robert S. McNamara.

James Larson, Miss Yoshimura's lawyer, is to begin the defense presentation Monday.
